Hey,
This looks like something that you’re going to need to use a child theme with.
If you’re unfamiliar with using a child theme, then you can read about that and download from here:
https://www.kadencethemes.com/child-themes/
I just tested this function that I found from here:
https://docs.woocommerce.com/document/woocommerce-display-category-image-on-category-archive/
add_action( 'woocommerce_archive_description', 'woocommerce_category_image', 2 );
function woocommerce_category_image() {
if ( is_product_category() ){
global $wp_query;
$cat = $wp_query->get_queried_object();
$thumbnail_id = get_woocommerce_term_meta( $cat->term_id, 'thumbnail_id', true );
$image = wp_get_attachment_url( $thumbnail_id );
if ( $image ) {
echo '<img src="' . $image . '" alt="" />';
}
}
}
And it works great on my site! You’ll want to place that into the functions.php file of your child theme.
The image that is output will be set in Products> Categories and then the “Thumbnail.”
Let me know if this works for you!
